Output filters are often used for noise suppression, which may have an influence on the control loop. To prevent output power losses, it may be necessary to compensate the control loop. No matter what switching regulator topology is used, as a result of the parasitic series resistor ESR, and the parasitic inductance ESL, of the output capacitor, th…
 
Switching controllers exhibit a residual ripple in their output voltage, which disturbs electronic devices, and may cause electromagnetic interference. Output filters are often used for interference suppression, which may exert an influence on the control loop. Compensation of the control loop may be required to prevent losses in output power. Down…
 
Chip bead ferrites are the best components for reducing high frequency noise above 10 MHz, but being the first components and the last components in the chain exposes chip bead ferrites to heavy transient currents. In this podcast, we discuss how circuit designers can now select parts that filter noise with minimal impact to power efficiency and wi…
 
Conducted interference occurs in the input circuit, whereby other electrical equipment can be disrupted, so the conducted interferences are first checked at the beginning of an EMC test of power supplies. In today's podcast, based off an Application Note, we discuss the procedure for examining differential mode interference in the input circuit of …
 
In today's podcast, we are diving into the world of infrared lighting; covering everything from data transfer to biometrics.

The market for Bottom Termination Components (BTCs) is growing rapidly, but these components have brought new challenges in design and assembly processes. The large areas of the solder terminals bring many advantages with them, like dissipating heat of the component. However, if the assembly process is not properly adjusted, then this can cause voi…
 
Advancements in lighting, heating, watering, and control systems have allowed the construction of vast, artificially lit, indoor greenhouses. One of the most significant future advancements in the viability of indoor greenhouses has been the advancement of LED technology. As advancements in their fabrication have progressed, LEDs have become the pr…
 
EMI is a common problem engineers face when designing a new application. How can a developer solve EMC problems on the circuit board or prevent them from occurring? What has to be considered and where does it make sense to use a filter? Which system impedances are there and what are the deciding factors for which filter topology should be used? In …
 
Choosing the appropriate components is vital for the efficiency of DC/DC switching regulators with relatively high input and output currents. A high-efficiency switching regulator is market-ready if it, and the end product, comply with all necessary EMC standards; meaning more filters must be included at the input and output to reduce interference.…
 
Recently, the need for disinfection technologies has skyrocketed. One of these technologies is disinfection using UV-C LEDs. Disinfection with UV-C LEDs can help reduce the spread of viruses such as the Corona virus as well as other germs. In this podcast episode, based on an application note and a WEbinar, the working mechanism behind disinfection…
 
This Application Note outlines the components needed to protect USB 3.1 devices and attenuate EMI that may cause the device to fail EMC testing. This will be demonstrated in USB Type-C dongle to characterize the effectiveness of the components. For information and components suitable for USB 2.0, please refer to the following Application Notes avai…
 
Modular jacks (MJ) connectors and cables are broadly used to bring Ethernet signal up to 10 Gb/s depending on the category of the product. It is also possible to deliver power through it with PoE. In this episode, we will study if recommendations for the WE-MJ connectors can be extended up to Type 4 and demonstrate the capabilities of modular jacks…
 
The trend to miniaturize wireless communication devices has led to decreased PCB sizes and increased component densities. Although this shift to miniaturized technology has aided many areas of electronic design, it constrains RF front-end design. Multilayer chip antennas are an interesting choice for engineers, who are restricted by cost and space …
 
Magnetic Field Interferences are increasing in electronic devices due to a number of factors including reduced separation distances of PCB’s, Integrated Circuits and many other sensitive components. Magnetically coupled communication technologies leads to more complex layout and proximity considerations. With Ferrite materials it is possible to man…
 
Rated current values found on datasheets serve as a guide for the selection of power inductors. However, the temperature rise in power inductors can be influenced by many factors that are not always reported in datasheets by all manufacturers giving a false sense of what the rated current values actually represent. In this podcast, we discuss how t…
 
Whatsup Good People! I hope everyone's doing good and staying safe. Here is the second episode of House of Yanos where I spin nice and chill vibey yanos tracks. This past month has been heavy due to the sudden lose of Yanos pioneers Mpura and Killer Kau. My heartfelt condolences to friends and family. There legacy lives forever in the music. Hope y…
